Long story short, I've decided to sell my desktop PC, having purchased an MBPr recently which I feel is lacking a little bit of power, I'm thinking on selling the MBPr as soon as I sell all the parts of the desktop PC and purchase this one: Refurbished 15.4-inch MacBook Pro 2.4GHz Quad-core Intel i7 with Retina Display (February 2013). Currently I have a i5 2.4GHz/4GB/128GB, which is getting complicated to have Windows too, graphics card ain't that great, and since I won't have a PC, and will do some video editing, flash, photoshop, etc. feels like I should make the switch. How reliable is the 802.11n compared to ac? Currently Time Machine is pretty fast on the 5GHz Time Capsule.
